Corsi Collection of Decorative Stones

view of stone 368

Corsi 368, approx. 145 x 73 x 40 mm, © Oxford University Museum of Natural History

OUMNH Number: 368  
Name and quarry location: almost certainly Travertino di Civitavecchia, from Civitavecchia, Lazio, Italy  
Geological description: Calcite travertine deposit, with algal(probably cyanobacterial) laminites. Coloured bands are tinted by hematite (red) and goethite (yellow).  
Comments: No records of travertines from the province of Milan have been found. This stone resembles a specimen from Civitavecchia, province of Roma, Lazio, Italy in the De Santis collection in Rome, which shows a similar 'way-up' of banded and crystalline layers, and makes Civitavecchia an altogether more probable source.  
References: Corpo Reale delle Miniere (1904) 98; Faramondi (1985) 18-19; Jervis (1889) 339-340; Price (2007) 57. Other examples: DeSantis coll. no. 283 and (especially) no. 284, Servizio Geologico d’Italia, Rome.
